EQUALIZING DRIVING DEVICE FOR BOBBINS.

SPECIFICATION forming part of Letters Patent No. 619,806, dated February21, 1899.

Application filed March 8, 1898.

To all whom it may concern.-

Be it known that I, JOSEPH E. TYNAN, a citizen of the United States,residing at Paterson, in the county of Passaic and State of New Jersey,have invented a new and useful Equalizing Driving Device for Bobbins, of

which the following is a specification.

My invention relates to machines in which threads are wound upon bobbinsplaced in a horizontal position uponthe machines. It is especiallyuseful where fine threads are to be wound from skeins onto bobbins.

The object of my invention is to provide a driving device to revolve thebobbin in order to wind the thread or threads upon it and that will atthe same time equalize the driving force applied to the bobbin. I attainthis object by the method shown in the accompanying drawings.

Figure 1 represents a front view of a bobbin in a horizontal positionmounted on a spindle running in bearings,with driving-pulleys to revolvethe bobbin. Fig. 2 is a side view of the same mechanism.

A is the bobbin on which the thread is to be wound.

A is a driving-head forming part of the bobbin.

B is the spindle on which the bobbin is mounted, and B is a driving-headaffixed to the spindle.

B is a spring upon the spindle used to hold the bobbin firmly thereon.

The pulleys O and D, mounted on the shaft E, will impart motionsimultaneously to the driving-head A, fixed to the bobbin, and to thedriving-head B, fixed to the spindle extending through the bobbin.

At F are shown bearings for the spindle B, which are attached to themachine. The ends of the spindle are confined by the sides of thebearing F, but are held clear of the bottom of the same, as shown at F.This allows the whole weight of the spindle, bobbin, and driving-headsto rest upon the surface of the pulleys O and D.

Heretofore the doubly-driven spindle and Serial No. 673,083. (No model.)

bobbin have not come into general use for several reasons. by having itsheads rest upon driving-wheels or a drum, the heads of the bobbin becomeroughened. Where fine threads are being manipulated and it is necessaryin subsequent operations to draw them from the heads of the bobbin, itis absolutely essential that the bobbin-heads should be smooth,,and forthat reason it is impracticable to use the heads of the bobbin fordriving purposes. Where the heads have not been used for driving, loosedrivingheads have been employed, being placed upon the spindle after thebobbin is placed thereon; but owing to the fact that the operator has tohandle these loose driving-heads, removing them from the spindle andreplacing them thereon every time a bobbin is doffed, the inconvenience,loss of time, and danger of dropping and losing the driving-heads arevery great.

In my invention I get the advantage of the double drive, while there isno roughening of the heads of the bobbin, and the operator has no loosedriving-heads to remove and replace.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. The combination with a winding-spindle having at one end adriving-head, of a bob bin having at one end a driving-head, anddriving-pulleys to come in contact with the driving-head upon thespindle and the driving-head upon the bobbin, when the bobbin is placedupon the spindle, to drive them simultaneously, substantially as and forthe purpose described.

2. A winding-spindle having a drivinghead, a bobbin having adriving-head, bearings for the winding-spindle, and means to drive thebobbin and spindle simultaneously, substantially as and for the purposedescribed.
